Gardener's Dictionary: Microclimate
Microclimate (n.): A microclimate is a location with a different climate than the area surrounding it. Microclimates can be as small as a few square feet, or it can be as large as many square miles. Your balcony garden will also have microclimates - a tree or building may provide shady, cool conditions on one half of the balcony, and unfiltered, bright sunlight can create hot, sunny conditions on the other. This offers two different growing regions in one small balcony garden.
